This next video shows the brand new 2013 SRT Viper GTS at the Fair Oaks Chantilly Chrysler Jeep Dodge Ram dealership in the United States. YouTube member RealMCR12 filmed the new all-American sports car when it was started up and revving in front of the entrance to the showroom.
The SRT Viper gets an 8.4 liter V10 unit producing 640bhp and 600lb-ft of torque. It has the most torque of any naturally aspirated engine in the world and a lightweight composite intake manifold, high-strength forged pistons, sodium-filled exhaust valves, new catalysts to reduce back pressure and an aluminum flywheel that reduces reciprocating losses. Altogether, a 25 pound weight loss over the previous model.
